Development of an efficient protocol for Robiquetia spathulata (Bl) J.J. Sm. an Endangered Orchid Species Through in vitro Techniques

Corresponding Author : Tapash Kumar Bhowmik (tapashptc@gmail.com)

Abstract :

Robiquetia spathulata (Bl) J.J. Sm. is an epiphytic endangered orchid species of Bangladesh and PM (Phytamax - Arditti, 1977) basal medium was best for seeds germination than KC (Knudson, 1946), MS (Murashige and Skoog, 1962), MVW (Modified Vacin and Went, 1949) media. Sucrose was highly favorable for germination as a source of carbohydrates than glucose and lactose. The highest mean increased length of seed originated seedlings (3.68 ± 0.22cm) and individual shoot bud (3.37 ± 0.18cm) were achieved on 0.8%…

Evaluation of phenotypic and genotypic variation of local pumpkin germplasm for improved breeding purposes

Corresponding Author : Romel Ahmed (romel-fes@sust.edu)

Abstract :

Pumpkin (Cucurbita moschata), a popular vegetable in Bangladesh, has a wonderful source of minerals, fibers, vitamins, antioxidants, and nutrients. Attempts were taken in the present work to select the best parents of pumpkin (Cucurbita moschata) among the 20 local germplasms for improvement breeding. The collected germplasms were evaluated for phenotypic and genotypic variations based on flowering days, vine length, fruit length and weight, yield, and pericarp length that were found to differ significantly (p< 0>

A Modular Landscape Model for Low Cost Settlement. Case study: Sylhet, Bangladesh

Corresponding Author : Mohammad Shamsul Arefin (msan_arch-arc@sust.edu)

Abstract :

This study aims to innovate an affordable landscape design model for under privileged urbanized areas of a growing cities. The lower income population from rural areas, frequently migrate to the urban areas for short or long-term basis to ease their poverty. This internal migration takes place for several reasons caused by manmade and natural disaster and dream of better life expectancies. These migrant people may get work and money in a certain number per single family, but it keeps them…

Synthesis and Characterization of Palladium Acetylide Complexes with Heterocyclic N-Donor Ligands

Corresponding Author : Muhammad Younus (myounus-che@sust.edu)

Abstract :

Mono- and bis-acetylide complexes of palladium with two different N-donor ligands of the type cis-[Pd(LL)(C≡CR)2] (LL = 1,10-phenanthroline,  R = C6H5 3, and LL = 2, 2-bipyridine,  R = C6H5 5) and [Pd(LL)Cl(C≡CR)] (LL = 1,10-phenanthroline,  R = C6H5 4, and LL = 2, 2-bipyridine, R = C6H5 6) were prepared by the dehydrohalogenation reaction between cis-[Pd(LL)Cl2] and phenyl acetylene ligand. The complexes were characterized by IR, UV-vis spectroscopy. These palladium-carbon σ-bonded complexes were sensitive to air in contrast to…

Distribution of Internal Rural-Urban Migration in Bangladesh: Application of Probability Models

Corresponding Author : Dr. Md. Zakir Hossain (mzhossain.bds@gmail.com)

Abstract :

The study of migration through probability models is very crucial for an in-depth understanding of the pattern, the volume of migration, and the factors acting on it. The study is devoted to the application of probability models to describe the pattern of household-level migration in Bangladesh. The probability models have been tested using a nationwide representative dataset of Bangladesh generated by the project “Rural-urban Migration and its Implications for Food Security in Bangladesh” under the National Food Policy Capacity Strengthening…
